Abstract: <PICT:0486478/III/1> <PICT:0486478/III/2> <PICT:0486478/III/3> <PICT:0486478/III/4> An apparatus for coating and decorating flat surfaces, such as textiles with liquids comprises a container 1 provided with a massive smooth nosepiece 2, a discharge opening 3 and a space 4, which serves as a collecting and distributing chamber for the fluid colouring matter to be applied by moving the apparatus over and in contact with the surface.  For interrupting the supply a spring-loaded valve 5 is provided, which in its closed position may or may not completely fill the space 4.  In a preferred form, Fig. 3, the valve stem 6 carries a flow-regulating plate 11 and a piston 8 both sliding in a tube 9.  In the position shown where the valve 5 has just been raised, liquid flows from the supply in the reservoir 1, through holes 10 in the tube 9 and holes 12 in the plate 11, out through the mouth 3.  To interrupt the flow suddenly, the valve is raised slightly higher, as in Fig. 4, so that the plate 11 closes the holes 10, while the suction produced by the piston 8 withdraws the liquid from the mouthpiece.  The mouth may be of any suitable shape. The apparatus may be moved over the surface to be coated by hand, or a plurality of such apparatus may be attached to a carriage 21, Fig. 7, and traversed by suitable mechanism over the surface to be coated. A handle 17 may be provided to open and close the valves of all the separate coating devices simultaneously, and springs 18 may be provided to maintain firm contact between the surface 22 and the mouths of the coating devices.  Patterns may be produced by suitable motion of the coating devices transversely to their direction of traverse and stencils or coatings of "reserves" may be used to protect certain parts of the surface from being coated.

IPC: H01H33/24
Filed: 1931-04-17
Abstract: 376,829. Electric switchgear. REYROLLE & CO., Ltd., A., Hebburn-on-Tyne, CHRISTIE, J., 4, Sidecliff Road, Sunderland, and AMER, D. F., 251, High Street, Jarrow, Co. Durham. April 17, 1931, Nos. 11427 and 20529. [Class 38 (v).] The fuses for the potential transformers in H.T. switchgear structures are mounted in insulating tubes formed of layers of insulating material interleaved with overlapping conductor layers of short length which act to grade the stress set up when the fuse has blown between the two ends of the fuse or between conducting members connected thereto. As shown in Fig. 1, the fuse G is mounted within an insulating tube K so that its lower contact engages the enlarged head H<1> of a conductor H passing to the potential transformer and its upper contact engages an internal conducting-ring K<2> which is connected on the outside of the tube to the pivot K<4> carrying an isolating switch blade L. The blade L normally engages a contact B<1> connected to a feeder B and a further clip contact on the member B<1> may be connected by the blade D of a second isolating switch to one of the terminals of a circuit-breaker A. To distribute the electric stress in the insulating tube K when the fuse has blown and to prevent corona discharge from the thin fuse wire during normal working a number of short overlapping metal conducting layers K<3>, Fig. 2, are interleaved with the paper layers in the part of the tube surrounding the fuse 9, the innermost layer being disposed around the lower fuse contact and the outermost layer around the upper fuse contact. A condenser bushing also surrounds the conductor H, the outermost layer of this bushing being arranged in contact with the short earthed metal trunk E<2> connecting the potential transformer casing E to the upper switchgear casing. Alternatively the condenser bushings may be arranged in the manner described in Specification 376,828. The fuse G is provided with an insulating handle G<2> so that it may be removed through the upper end of the tube K. To prevent the removal of the fuse while the transformer is alive the upper end of the tube is normally closed by a hinged flap J<1> which is interlocked with the isolating switch L in such a manner that the latter has to be placed with its blade engaging an earthed contact L<1> before the flap can be raised. A limiting resistance may be mounted above the fuse G so as to be connected in series therewith and adapted to be removed with the fuse, especially when a liquid-filled fuse is employed.
